Abstract
Systems and methods for impact detection in accordance with embodiments of the invention are disclosed. In one embodiment, a vehicle impact detection system includes an acceleration sensor, a storage device storing an impact detection application, and a processor, where the impact detection application directs the processor to receive acceleration information using the acceleration sensor, filter the acceleration information to attenuate noise, determine an occurrence of an impact by detecting an acceleration from the acceleration information that exceeds a threshold for a time period, detect an angle of the impact with respect to a forward direction using the acceleration information, and trigger an impact detector signal.
